INTERMITTENT-OPERATING MECHANXSM.

To all fui/tom t may concern:

Be it known that I, EMIL R. BITTNER, a citizen of the United States,residing at Victoria, R. i?. D. #3, B0X 2S, in the county of Victoriaand State of Texas, have invented certain new and useful improvements inintermittent-@pending Mechanism, of which the following isspecification.

The invention has for an object to edect an improvement in automaticregulating meansrfor wind mills, applicable to use in assuring a supplyof water in a tank at a mean level without liability of too frequentoperation of the control. aim'is to give an improved and simpleconstruction of ratchet and pawl and means for holding the pawlsoperative at one time and inoperative at another time.

lt is alsosought to give such a device as will not be easily deranged,which will not wear out quickly, and which may be produced at a lowcost. Another purpose is to present an embodiment of the invention whichwill be applicable to use with any usual construction of windmillalready in use, without modication of the original structure.

Additional objects, advantages, and features of invention will appearfrom the construction, arrangement, and combination of parts hereinafterset forth and shown in the drawings, where Figure l is an elevation of awindmill pumping plant having the present embodiment of my inventioninstalled thereon.

.Fig 2 is a detail of the mounting of the .vaney and its control.

Fig. 3 is a plan view of the control.

o Fig. t is a detail of connections between the spider andl float.

rilhere is illustrated a tower 10 having a tank l1 of usual formthereon, supplied by any suitable pump, not shown,l operated by means ofthe pump rod l2 connected in a familiar way with the wind-Wheel 13. Thewheel 13 isheld in operative or inoperative position by means of thevane le including the frame l5 pivoted on the rotating frame 16 `bywhich the wheel 13 and the drive connections therewith are carried. Thevane is held yieldably in operative position by means of the spring 17,yand is drawn to inoperative position by means of the cable 18 extendingaround. suitable pulleys 19 and thence downward ythrough the tower to apoint ofjcontrol. These details are well Specification of LettersPatent.

known in the art and do not comprise a novel part of my invention.

The point of control in the present case is a platform Q0, located onthe tower over the tank ll and having suitably mounted thereon a bracket2l upon which there is revolubly mounted a ratchet wheel 22 by means ofa stub shaft 23. The outer end of this shaft also supports pivotally aspider 24, having two wiper arms 25 and 26 carrying small rollers 27 attheir outer ends adjacent the 'perimeter of the wheel 22. The spideralso includes the weight carrying arm 2S, upon which there islongitudinally adjustable a weight 29 consisting of a suitable'body ofmetal centrally bored and receiving the arm 28 slidably therethrough, aset screw being provided to secure the weight in adjusted position. rlheshaft 23 is extended through the bracket 2l to a second smaller' bracket3l, spaced from the first bracket, a drum 32 being carried upon theshaft between the brackets. Pivoted upon these brackets there is a yokemember 33, having a lever arm 34 extended therefrom and pivotallyconnected to the pump rod as at 35. p

The yoke has pivoted thereon a pawl 36, hanging so as to engage theratchet under reciprocation of the pump rod, a weighted extension 37being projected therefrom to bear the pawl against the ratchet wheel.

|The pawl is provided at the side toward the spider with a lateralflange 38, extending divergently outward and upward from the arc ofmovement of the outer end of the arm 26 which is adjacent thereto, theflange being also alined with the plane of oscillation of the arm. Theyoke is so pivoted and the pawl 36 so located thereon that reciprocationof the pump rod will operate the ratchet wheel and rotate the drum 32.

In the inoperative position of the control-that is to say, the positionin which the windmill is left free to operate the pumpthe weighted arm28 is approximately or nearly vertical, resting against a checked lug 39on the bracket 2l, while the arm 26 lies with the wiper 27 thereonengaged with the flange 38 of the pawl 36 so as to hold the pawl indisengaged position, permitting the pump rod to reciprocate withoutoperating the ratchet wheel. The arm 25 at this time is approximatelyhorizontal, the wiper thereon being engaged with a iiange 38 formed on aratchet 40 having an inward` weighted extension 4l by which its upperpart isborne inwardly toward the ratchet wheel. The arm inthis positionholds the pawl il() disengaged also, the flange 38 being downwardlydivergent from .the arc ot' movement' of the wiper 2 on' this arm. Thespider is movable from this position in the direction of divergence ofthe pawl iianges to permit them to tall inwardly and engage the ratchet.Connected to the arm Q5 there is a link i2 extending (lov\n\,.'aitllyand connected to' a rocking arm e8 normally horizontal, p'ivotedintermediately of' its length on the tower trame, 4 To the opposite endof the arm 43 a second lower link i4 is connecte ed, entend'ing into thetank ll, where a. iioat l5' is engaged slidably thereon, the movement ofwhich on the link is limited npper` andl'ower stops Li6 secured` to thelink.

, lt will be seen that when the level oit the water in the tank' fallsto a sufficiently low point'the float will engage the lower check, andwhen it rises a cert-ain height the upper checkwill be engaged by thefloat. The last mentioned action will result in the link 4t2 pulling'the spider'V toward disengaged position, and after the weight 29 hasmoved a Y certain distanceV it will fall rapidly moving the spider toentirely disengaged position, andholding it there until the weightengages the lower check whenthe spider will be returned to engagedposition, lifting the pawls from engagement with the ratchet rss wheel,Y v

Connected to the drum 32 there is a cable 18, before mentioned, so thatwhen the lower check is engaged and the ratchet and pawls helddisengaged the vane 1s 'tree to move C .9 under action of the spring l?to operative c position, the wheel l2 then being held so as to berotated by any wind ot snicientforce and operating the pump to lill thetank. lWhen the upper check e6 isl engaged and the ratchet and pawlallowed' to engage the ratchethwheel, the reciprocations of the pumpro'dwill canse rotation ot the ratchet wheel and drum through the agencyot the yoke 33 and pawl 36, winding the cable 1S so as to draw the vanele to inoperative position. Any tendency of the wheel 13 then to operatewill be checked by the engagement of the pawl 3 with the ratchet, byreason oi the connection of the pump rod thereto and the tautening ofthe cable i8.

Y The form of the connections between the lioat andspider maybe variedto suit variousy conditions and types of construction with which it beemployed, andthe control device may be mounted in other" situationsthanthat shown, as, for instance, it may be mounted on the top of thetank' ll, and theV lower link connected to thearm 26 of the spider, orrconnections made between thespider anda neat in a tank at a disiicve IHlie Bowler bym/LS' Suit/ able links and bell cranks, these details beingsn'iiiciently obvious not to require illustration.

lt is desirable that the connection between the links and the arm Q5 bemade with a lost motion connection, in order that as soon as the spiderhas been moved a little way it may fall immediately into position toallow operation of the drum, under action oi the weight 29. ills shown,this connectionA comprises rotating pin et? having. an apertured headthrough which the upper end of the link e2 is sli'dably engaged The linkis provided with collars 4:9 suitably spaced thereon to' permit theYaction described, By' this arrangement the float link 44 will notrequire a great degree of movement in order to set the controllingmechanism pinto' operation to stopthe mill, and it will'be possible toallow the tank toV lillto a high point without liability of runningovera lit the controlling device is located at a considerable distancefrom the tank, VwhichV be found desirable to make connections with thearm 2 8, instead of the one 25, as dotted in Fig. 2. A Y

ln Fig. e there is shown a preferable cone struction of the connectionsbetween the spider and link e2, which consists in Vforniing alongitudinally extending lug 5G on the arm 25, in which there isformed'Y an oblongv slotl 5l, throughwhich the link is engaged. Thecheck collars'eQ are engaged upon the link above and below the lugs, aswith the rotating pin previously described. Similar lugs 52 one ofwhichl is shown may be :termed on the arms 26 and Q8, to be used in casefound desirable in making connec`- tions with a slope point.
